To all whom) t may concern,.-

Be it known that I, CHARLES B. RIsLEY, acitizen of the United States,residing at Princeton, in the county of Gibson and State of Indiana, have invented certain new and useful.

Improvements in Rod-Packing and I do hereby declare the following to be a full, clear,Y and exact description of Ythe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This inventiony relates to packing for piston-rods, plungers, and other similar cylindrical bodies; and it consists in the novel construction of the same, as hereinafter fully described and claimed.

In the drawing the figure is a vertical section through a stning-box-provided with packing-rings according to this invention.

A is the stu ding-box, provided with a gland B, and C is the piston-rod, which slides in the Stuffing-box.

The packing consists of one or more rings D. Any desired number of similar rings may be used. Each ring consists of a packingsection d and a filling-section e. The packing-section is odset upon one side of the i-ling-section, so that a projection f is formed next to the rod.

G is a water-seal chamber formed by the packing-ring between the lining-section and the rod. The packing-section has a solid core g, of india-rubber or other suitable packing material, which is preferably round incrosssection, and the filling-section has a similar core h.

His exible packing material, such as cloth or canvas, which is Wrapped around the cores and preferably wrapped several times around the round core g.' The core t is preferably square in cross-section; but the forms of the 4cores may be varied in carrying out the inner, as by adhesive material or cement.`

What I claim isl. A packing-ring formed of a round core and a rectangular core *arranged one above the other so that the said round core forms a projection upon one side of the packing-ring, and'exible material wound upon the said cores and binding them together.

2. A paclging-ringformed of two cores of unequal size secured one above the'other so that the larger core forms a projection upon one side of the packing-ring, and flexible material wound upon the said cores and extending between them and binding the said cores together.

In testimony whereof I aftix my signature in presence of two witnesses.
